Mercedes-Benz GLS Maintenance Schedule

The Mercedes-Benz GLS is the pinnacle of luxury SUVs, offering a perfect balance of space, power, and refinement. To keep your GLS performing at its best on the roads of South Texas, from Corpus Christi to Robstown, Port Aransas, and beyond, following a proper maintenance schedule is essential. Below, we’ll cover the key service intervals, along with the manufacturer-recommended tire sizes, oil type, and battery size to help you stay on top of your GLS’s needs.

Mercedes-Benz GLS Service A & Service B in Corpus Christi

For your Mercedes-Benz GLS, two key service intervals ensure your SUV maintains optimal performance in South Texas’s coastal environment—Service A and Service B. These services alternate every 10,000 miles.

1. Service A – Performed at approximately 10,000 miles or 1 year, whichever comes first.
   • Synthetic motor oil replacement (0W-40 or 5W-40, Mercedes-Benz-approved)
   • Oil filter replacement
   • Brake inspection
   • Tire pressure check and adjustment
   • Fluid level checks and corrections
   • Reset maintenance counter
2. Service B – Performed at approximately 20,000 miles or 2 years, following Service A.
   • Includes all Service A tasks
   • Cabin air filter replacement (for dust and pollen)
   • Brake fluid exchange
   • Inspection of suspension, steering, and belts

Alternating between Service A and Service B every 10,000 miles keeps your GLS in top condition, ensuring it’s ready for anything from family trips to the beach to navigating the bustling streets of Corpus Christi.

Additional Key Maintenance Intervals

Beyond Service A and B, additional tasks are necessary to help keep your GLS performing like new:

• Every 10,000 miles: Oil change, brake inspection, and tire rotation (Service A)
• Every 20,000 miles: Cabin air filter replacement, brake fluid exchange (Service B)
• Every 40,000 miles: Transmission fluid check, engine air filter replacement, and suspension inspection
• Every 60,000 miles: Spark plug replacement, coolant system inspection, and battery check

Following these service intervals ensures that your Mercedes-Benz GLS continues to operate luxuriously, and is ready for the Texas heat and humid coastal air.

Recommended Tire Sizes for Mercedes-Benz GLS

Your GLS needs the right tire size for optimal handling and comfort, especially when driving through South Texas’s varied landscapes. Mercedes-Benz recommends the following tire sizes for the GLS, depending on the model and trim:

• Standard Tires: 275/50R20
• Optional Upgrades: 285/45R21 or 295/40R22

Proper tire care, including regular rotations and pressure checks, ensures your GLS rides smoothly whether you’re commuting in Corpus Christi or taking a scenic drive along the Texas Gulf Coast.

Recommended Oil Type for Mercedes-Benz GLS

Using the manufacturer-recommended oil is crucial for maintaining engine performance, especially in hot, coastal climates. Mercedes-Benz recommends synthetic motor oil that meets the MB 229.5 or MB 229.51 specification. Commonly recommended options include:

• 0W-40 or 5W-40 synthetic oil

These oils are formulated to handle extreme heat and long driving distances, making them ideal for Texas’s weather conditions.

Recommended Battery Size for Mercedes-Benz GLS

Your GLS relies on a powerful battery to support its advanced electronics and driving systems. Mercedes-Benz recommends using a Group 49/H8 battery, which provides the right power and fit for your GLS. Specifically, your battery should meet the following specs:

• Battery size: 12V Group 49/H8 (850 Cold Cranking Amps, 92 Amp Hours)

Regular battery checks and replacements as needed will ensure your GLS starts reliably, even in South Texas’s high heat.

Planning for Mercedes-Benz GLS Maintenance Costs in Corpus Christi

Planning for maintenance costs is crucial. Here’s a general idea of what to expect for standard services:

• Service A: Typically ranges from ~$250 to $450, depending on dealership pricing.
